IIAs have been receiving a fair amount of media attention lately (at least in Canada). In case you haven’t caught any of this, or aren’t forced to hear me talk about it in a colloquium session, a brief refresher: Investment agreements (IIAs) are generally bilateral investment treaties (BITs) or embedded in FTAs, and commit countries to maintaining stringent investor protection standards. Controversially, they allow investors from one of the states party to the treaty to initiate arbitration proceedings against the government of the other. Arbitrators are then charged with deciding on the legality of domestic measures affecting an investor, which may range from fairly clear cut cases of corruption to honest attempts to regulate in the public interest.
